What is the speed, in m/s, of a wave on a cord if it has a wavelength of 4 m and a period of 0.5 s?

Given

Wavelength = 4 m

Time (t) = 0.5 sec

Speed ( S) = ?

Explanation:

first we should calculate the frequency

so Frequency

= 1/t

= 1/ 0.5

=2 Hertz

Now Speed = wavelength * frequency

= 4 * 2

= 8 m/s

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

it breaks and dirupture other materials and other sencews from the bottom
